HACKLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 404,215, dated May 28,1889. Application filed April 13,1888. Serial No. 270,604. (No model.)

making part of this'specification, and to the letj ters and figures ofreference marked thereon.

Similar letters of reference indicate corresponding parts in all thefigures of the drawings.

The object of my present improvements is to devise an efficientstructure for combing and preparing manila, sisal, and American,Russian, and other hemp-or analogous fibers;

and my invention consists of certain novel parts and combinations ofparts designed for this purpose.

The following is a description of the accompanying drawings, wherein isillustrated a machine embodying all the several features of my presentinventionin combination. My invention is not confined, however, to thespecific devices and combinations of devices illustrated and describedherein.

The points of novelty which I desire to secure by this patent will bespecifically pointed out in the claims concluding this specification.

Referring to said drawings, Figure 1 illus trates a side elevation of myimproved hackling-machine with one of the side plates of the framecarrying the combing-chain removed, and certain parts of the structurebroken away to illustrate more clearly the details thereof. Fig. 2illustrates a part of the combing-frame and a part of the delivering anddetaining cylinder, and Fig. 4. a part of the combingpins. Fig. 3illustrates a carrying-wheel and part of the combing-chain and the guideat the delivering end of the combing-chain, by means of Which theindividual teeth are given an inclination which causes them to withdrawfrom the hemp and permit it to pass out through the delivering-rollcrs.Fig. 5 shows the detaining-cylinder and the guides in detail near thesame, by means of ing a cross-section of the device shown in v Fig. 6.

Referring to Figs. 1 and 5, A A are a pair of feed-rollers, throughwhich the hemp is fed into the machine.

B is a wheel or cylinder, the periphery of which is provided with radialslots or tracks 0 C. In each of these slots a bar, D, furnished withpins D, is set, which is caused to travel radially out and in as thewheel revol ves, by means of any suitable device, such as stationaryside plates of the wheel B provided with grooves U. These bars arecaused to slide in said radial slots as the wheel revolves, so that thepins as they pass the feedrollers will be projected to penetrate andfirmly engage the hemp entering the machine and carry it around to thehackling-frame.

This device is illustrated in detail in Figs. 5 and 6, in which X is astationary plate keyed to the stationary axle V by the key W, and havingcutupon its face the groove U.

E is an apron set below the Wheel Band extending from the feed-rollersto the combingchain to prevent the fiber dropping away from engagementwith the detaining-pins D.

F is a frame in which the carrier-whee1s G G are set.

H is a linked chain carrying bars I, furnished with pins 0 0. (See Fig.4.)

I are guide-dogs set on each end of the bars I, and J J are pegs set inthe guide-dogs I.

K, L, M, and N are guides to direct, by means of the dogs in the ends ofthe bars I, the inclination of the pins 0.

P P P P are delivery-rollers, by means of which the fiber is dischargedfrom the machine.

Power is applied to the machine through the shaft U", carrying thepulley U. On the same shaft and keyed to it isa gear-wheel, T, meshingwith the teeth of the gear-wheel Q, which gears into the wheel R, andwhich latter in turn drives the delivery-rollers P P. By means of abelt, Z, power is transmitted from the pulley U to a pulley, V, whichactuates a shaft, W, to which the gear-wheel \V is attached, the teethof which last-mention ed wheel mesh in a gear-wheel, X, keyed to whichis a pinion, X, which meshes with gears on the detaining-cylinder 13.

The operation of the machine is as follows: Hemp is fed in between therollers A A, where it is caught by the pins 1), which are caused toproject and pierce the mass of the fiber as it leaves the rollers andpenetrate through its entire depth down to the apron E. As I have said,any suitable device may be employed to cause the pins D to advance andretreat such, for instance, as the stationary groove 'l, with which thelaterally-projecting pegs at the ends of the bars I) engage, and bymeans of which their degree of projection at any position is definitelydetermined. For reasons hereinafter more fully pointed out, I prefer tohave the wheel. 13 and the hackling-chain F placed near together aspossible. For the purpose of avoiding interference with the guide-dogs Ion the hackling-chain, l have illustrated these pins 1) being withdrawnor as retreating as they approach the hackling-teeth. Now as the fiberis carried forward by the revolution of the wheel I it is caught by thehaekling-teeth O, which are moving at a higher velocity than the pins1), the effect of which is to comb the fibers, the function of the pins1') in this operation being to hold the fibers while they are beingoperatcd upon by the teeth 0.

Referring to the hackling device, it will be observed that as theguide-dogs I, attached to their several pivots on the flexible chain ll,approach the wheel. G (partially broken away in. Fig. 1, but shown infull. in Figs. 2 and 5) the project-ions J strike the guide N, an d asthe bars progress the teeth are inclined forward more and more in thedirection of their motion, so that they can approach very near towithout interfering with the apron E or the detaining-cylinder. hen theymeet the hemp which is being carried slowly forward by the wheel 13,their inclination is such that they readily penetrate and comb itthroughout its entire mass. \Yhenthe guide dogs I arrive at the end ofthe guide N, the pins J strike the track K and the pins J pass in frontof the end of the guide N, engaging with the track L. From the timethese bars leave the carrier G until they reach the carrier l theirposition is determined by the tracks K L, and as long as they areoperating upon fiber which is still held by the detainingcylinder theteeth are inclined forward, thus preventing the fiber riding up over thetop of the teeth. At the upper part of the frame is a guide, M, whichengages with the pegs J on the longer arm of the dogs, by means of whichthe teeth are inclined backward, or in a direction opposite to theirmotion, so that they are automatically drawn out of engagement with andcease to operate upon the fibers, which are then caught and led out ofthe machine by the delivory-rollers I, while the chain at this point isdescribing the arc of a smaller circle. The inclination of the pinsbackward, or in a direction opposite to their motion, serves to preventthe deliveryrolls, which preferably move faster than the combing-chain,from drawin the fiber up and over the combing-teeth. On the contrary,the inclination of these teeth is such that the fiber is held by themand combed by being drawn through them by the delivery-rollers, thecombing-teeth acting at this time in a sense as detaining-teeth. Thecombing-teeth are preferably made to incline forward as long as thefiber which they are acting upon is held by the detaining-tee th 1'),and are made to incline backward as soon as the fiber which they areacting upon is caughtbetween the delivery-rollers. This is an importantfeature of my present invention.

It will of course be understood that in operation the wheel 13 turnswith a left-hand revolution, while the hackling-ehain ll is propelled bya right-hand revolution of the carriers G G, so that where the twoapproach each other the direction of their movement is the same whiletheir velocities differ, the hackling-chain moving much faster than thedetaming-cylinder.

The advantages of my improved hacklingmachine over all others in useare, among other things, that by the peculiar design, relat-ion, andcoi'istruction of the detaining and hacklin g devices I am able to bringtheir teeth close together, and, indeed, if desired, and as illustratedin the drawings, have them intersect, thus avoiding the possibility ofany hemp escapin g without being properly combed throughout its entirelength by the hackling-teeth, while the shape of the path which thehackling-chain follows, as well as the arrangement and inclination ofthe teeth, avoids the danger of carrying the stock past thedeliveririg-rollers, and thus preventing its discharge from the machine.It also prevents the stock being drawn by the delivery-rollers over thetop of the combing-pins.

It will be observed that the hacklingchain describes an irregular curve.At the pulley G the chain describes the arc of a small. circle. As itrises above said pulley its path is a curve ap n'oximating the curve ofthe periphery of the detaining-cylinder. It then follows the are of alarger circle, rising above the detaining-teeth and approaching thedelivery-rolls. At this end the chain again describes the arc of asmaller circle, and by any suitable path returns to the pulley G. Thispath substantially is what I call an irregular curve. By thisirregular-curved course I obtain all the advantages of having thecombing-pins travel in a long rising curve from the detainingnns towardthe delivery rollers, and also am enabled to have both thedetaining-pins and the deliver -rollers set very near to the path of thehackling-chain a matter of considerable importance in this class ofmachines, since it enables the device to comb the iiber perfectly fromend to end and to readily feed and strip the fiber.

ITO

My improved machine is obviously capable of various modificationswithout departing from the general principle and scope of my invention,and my various improvements may be employed separately, instead of incombination, as illustrated and described.
